THREAD OILER on morsrnmtn Application filed February 20, 1926. Seria1 No..89,529.

My invention relates to what are ordinarily termed oilers for yarns or threads by which they are oiled, or wet, or otherwise treated by a liquid during the passage through the device.

,The main purpose of my invention is to equalize the amount of treating liquid taken up by different parts of the fiber.

A further purpose is to submerge the yarn, or other fiber, in the liquid and yet to render the time of treatment wholly independent of the depth of liquid in the device.

. A further purpose is to submerge the fiber in the treating liquid by afloat whereby the extent of submersion will be maintained uniform by the uniformity of the position of the float with respect to the surface of the liquid.

A further purpose is to simplify the construction of the oiler as well as facilitate placing and replacing the fibers 1n the device. A further purpose is to provide a wiper for the thread or fiber as it comes from the oiler.

A further purpose is to provide a drag for the fiber to prevent overrunmng of the fiber when it is drawn at a non-uniform rate.

A further purpose is to reduce the splashing from an oiler or moistener.

Further purposes will appear 1n the specification and in the claims.

I have preferred to illustrate my invention by one main form only, with slight mod fications, selecting a form which is practical, eflicient, simple and inexpensive, and which at the same time well illustrates the principles of my invention.

cleaning, freedom ofzaocess and clearness of View as to height of liquid, I prefer to make the vessel 5 of glass The-length of thefcontainerwill depend largely upon the number of fibers which are to be oiled in thecontainer. In the. present TES PA-TENT oFF E;-,+,

my invention, carrying a wiper '60 For convenience inlmanufacture,iease of case I have 'provided' for two well spaced Within the con aiiier I provide a float 6 which is intended to depress the fibers 7 to a uniform extent beneath the surface of the liquid 8. So far as my invention is concerned it is immaterial whether the fibers are depressed by passing beneath the body of the float as in Figures 1, 2, 3 and 6 or passed through an opening in the body be} neath the liquid surface as in Figure 4, or passed through guides carried by the float and hence maintained by it at uniformdepth beneath the liquid surface as in Figure 5..

My invention in itsbroader aspects is inde-f pendent also of the character of guiding means employed and of whether there be any guide carried by the float or by the container 5. The guiding function can be performed by wholly external guides, as in Figure 6.

The structure in Figures 1 and 2 utilizes a long float 6, having guiding grooves 9 through which the fiber passes and by which the fibers are separated within the liquid. The use of a round float in this figure reduces friction upon the fibers by permitting the float to turn. Side and end play are, prevented while providing an enlarged reservoir for the oil, or other treating liquid, by the use of ribs 10 and 11. Grooves 12 at the top perform a guiding function there.

In the form shown in Figure 4 the float 6 is apertured at 13 to provide openings through which the fibers pass and are guided. It performs the same functions as in the form in Figures 1-3, except that the float cannot rotate.

In the form shown in Figure 5 the float carries uides 14 by which the fiber is depressed beneath the liquid and guided in its passage through the liquid. These guides may be made of wire tightly fitting the float to retain the guides in. position by their grip upon it. \Vhere the float is free from danger of rotation, as in this form, these guides need not be completely closed at the bottom but are nevertheless preferably in the form of spirals, loose enoughfor the thread to be passed into them freely in the spaces between the turns and without necessity for threading through the apertures.

In the form shown in Figure 6 the guiding function is intended to be performed primarily by outside guides 12 of any suitable character, wholly separate from or forming part of, or mounted upon other mechanism. Here the guides may also be of spirals loose enough to permit side inertion of the fiber. A plain stick float 6* is used.

Separate guides are not so satisfactory as guides forming part of the device as in the other forms.

In the form shown in Figures 8; 9 and 10 a float 6 is shown intended to oil a single fiber only. It is grooved at 9 and its ends 15 fit within the grooves 16 in the side walls of a perfectly plain vessel 5. In conjunction with this form I have shown a drag and wiper equally desirable in connection with any of the other forms and which can be applied to any vessel. There is no reason why it can not be made integral with the vessel and I have shown the drag and wiper as separable from it for the reason only that I prefer this separability in order that the drag and wiper can be cleaned effectively with less trouble.

In the means of attachment shown, equally suitable for the other vessel illustrated, the combined drag and wiper 17 is provided with a bracket 18 in the form of ears 19 which straddle the wall 20 and bear on opposite sides of it. If applied in single form to vessels of the character of that shown in Figure 1, it would be applied to such parts as 20 of the wall of this vessel.

With any machine having intermittent feed, such as a full-fashioned hosiery machine, it is desirable to prevent overcasting of the thread. I do this by putting a drag upon the thread by guiding it through a tortuous passage here provided by staggered pins 21. At the same time I provide for drainage of these pins in order that they may perform a wiping function to the best advantage. I provide also an additional wiper in the form of ribs 22, preferably diagonal to the general path of the thread so that, with the slope of the base 23 upon which they are mounted, there will be free drainage through the spaces between the ribs for any excessive oil or other liquid which the fiber may have carried from the pool of liquid.

- By this construction, the means for stopping the overcast is made to still further equalize the oiling or wetting of the fiber, as any undue amount of oil or other liquid taken up by the fiber during an interim in the feed will be removed from it during the progress of the fiber through the wiper.

The combined drag and wiper is effective to substantially eliminate splashing as vibration of the thread is greatly reduced and the excess of liquid normally splashed is taken up by the wiping action.

My drag is adjustable since, by omitting one or more of the turns of the tortuous path (1. e., skipping one or more pins) the amount of drag is lessened. It can thus be adapted to the needs of the particular fiber handled.

My drag and wiper is the most desirable construction for this purpose known to me.

Iappreciate however, that with somewhat less advantage a drag and wiper of fiber material such as felt, possessing capillary attraction, could be used, separately or that it could be used to assist in the action, placing it on a drain-board and passing the thread over or under it. tion is shown in Figure 10, where the felt pad 24 rests upon the drain-board and receives oil or other liquid from the thread 7. This pad 24 is shown as located partly at 24 about the pins and between the ribs (which thus hold it in place) and partly at 24 beyond the last rib. It may occupy either or both positions. It can of course be placed ahead of the drag shown in Figure 10, as at 24 and can be used without the ribs or pins or without either of them as desired.

It will be evident that the uniformity in the depth of submersion of the fiber, the draining drag upon the fiber as it leaves the liquid and the draining wiper all combine to equalize the extent of oiling or wetting of the fiber. It will be further evident that the arched relation of the wiping ribs insures contact of each of the ribs with the fiber to wipe it and that the diagonal position of the ribs and the general slope of the support insure drainage, not only for the ribs themselves but for the pins used as guides and wipers and providing the tortuous passage.

In operation the fiber need only be passed beneath the float, in most of the forms, to find its own guided position in line with the guides in the walls of the vessel or separate guides upon or independent of the vessel.

The drag ensures that the speed of passage of the thread or fiber through the liquid shall Such a construc be that of the mechanism drawing it, thus giving uniform extent and time of immersion during feeding operations. 7

Such tendency to splash as is due to whipping of the thread where the feed is intermittent is taken care of by the drag.

The proper performance of the wiping function involves some drag. I have aimed to provide for additional and adjustable drag where this is desired with a variety of wiping means capable of independent or combined use. The wiper takes up and drains away from the thread any excess of oil or liquid carried over, preventing splashing and making uniform the oilor liquid content of the thread or fiber.

Replacements of threads involve a minimum of time and trouble and so long as the bottom of the float is above the bottom of the vessel the extent of immersion of the fiber is uniform.

In view of my invention and disclosure variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain part or all of the benefits of my invention without copying the structure shown, and I, therefore, claim allsuch in so far as they fall within the reasonable spirit and scope of my invention.
